For example, I prefer to sort my recipes by style, not name -- every time I close and relaunch BTP it reverts to sorting by name. Not a showstopper, but an annoyance.

I also always want Recipes > On My Computer to be open, but every time I close and relaunch BTP those are "closed". Ditto for any other sections in the sidebar that I leave open when I close the app, I'd prefer them to be open next time I launch.
